摘要： 本文提出了一种基于FeFET的有源像素传感器，该传感器通过利用铁电层的多域极化状态，在传感器内执行乘加（MAC）操作。 所提出的设计将可编程FeFET集成到3晶体管像素电路中，其中FeFET的非易失性电导编码权重，光电二极管的电压降编码输入。 它们的相互作用生成与乘积成比例的输出电流，实现像素内的模拟乘法。 通过沿共享列线对输出电流进行求和来实现累加，在图像传感器阵列内实现完整的MAC功能。 使用45 nm CMOS模型进行的大量HSPICE仿真验证了该设计的运行并确认了其可扩展性。 这种紧凑且低功耗的架构减少了数据移动，使其适用于实时边缘计算、类脑视觉和安全传感应用。 显示英文摘要

摘要： This paper presents an FeFET-based active pixel sensor that performs in-sensor multiply-and-accumulate (MAC) operations by leveraging the multi-domain polarization states of ferroelectric layers. The proposed design integrates a programmable FeFET into a 3-transistor pixel circuit, where the FeFET's non-volatile conductance encodes the weight, and the photodiode voltage drop encodes the input. Their interaction generates an output current proportional to the product, enabling in-pixel analog multiplication. Accumulation is achieved by summing output currents along shared column lines, realizing full MAC functionality within the image sensor array. Extensive HSPICE simulations, using 45 nm CMOS models, validate the operation and confirm the scalability of the design. This compact and power-efficient architecture minimizes data movement, making it ideal for real-time edge computing, neuromorphic vision, and secure sensing applications.
